New to SAOImage DS9 7.1

Catalog Matching
DS9 now supports catalog matching. From the catalog menu, the user selects two currently loaded catalogs, an error radius, and matching function. The user may request all sources that are present in both catalogs, or in one catalog and not in the other. Each catalog need not to be specified in the same world coordinate system.

Enhanced Plot Tool
In addition to a Line Plot Tool, DS9 now supports additional Bar and Scatter Plots Tools. The GUI for the plot tools have been enhanced and new features have been added including statistics and data lists. Each plot tool supports multiple data sets and custom plotting options.

Catalog Scatter Plots
The user may now plot the results of two columns of a loaded catalog as a scatter plot. A selected region on the image will highlight the corresponding row and plot point. Likewise, a selected row or plot point will highlight the corresponding image region.

Interactive Region Analysis
DS9 regions now support interactive region analysis. The analysis tasks are enabled by selecting the Analysis Menu in a region's dialog box. Interactive analysis tasks includes statistics, data cuts in 2D and 3D, and radial profiles.
